SURFACE PREPARATION
All surfaces must be clean, dry and be free from dust, grease, wax, oil, laitance, curing compounds and all other
contaminants likely to prevent the adhesive bonding. Highly porous substrates must be primed with ASA Multiprime
prior to tiling. Concrete should be allowed to cure for at least 28 days and cement render 7 days prior to tiling. A
wood fl oat fi nish is preferred. Smooth steel trowel fi nished concrete must be mechanically abraided to increase
adhesion. Waterproofi ng membranes must have dried in accordance with the printed directions on the packaging.
EXPANSION JOINTS
Movement joints must be incorporated in the tile layout in accordance with AS3958.1-1991 clauses 5.4.5.1 to 6.
MIXING
20kg of Excelfl ex Trade powder requires 6 litres of clean water which produces 18 litres of mixed product. Add a
measured amount of clean water into a clean container and sprinkle Excelfl ex Trade powder slowly into the liquid
with constant stirring. Eliminate lumps. Mix to a thick toothpaste consistency. Allow to stand for 2 minutes. Mix
again. The adhesive is now ready to use.
APPLICATION
Apply the mixed adhesive to the prepared substrate using the appropriate notched trowel for the size of the tile
being laid. A minimum of 1mm bed thickness for walls and 3mm for fl oors must be achieved. Ensure that the
bedded tiles are fully supported by the adhesive with no voids underneath or behind. Lay tiles into the adhesive
before it skins. The adhesive may also need to be applied to the back of the tiles to accommodate the required
levels. Do not disturb tiles until the adhesive has dried. Commence grouting after 24 hours when tilework is fi rm.
GROUTING
Use the appropriate ASA grout, allowing joint widths of 1.5mm to 6mm for walls and 3mm to 12mm for fl oors as
per AS3958.1-1991 clauses 5.4.6.
CLEAN UP
Excelfl ex Trade can be removed from the surface of the tiles using a damp cloth while the adhesive is still wet.
Tools and equipment can be cleaned with warm water and detergent prior to adhesive drying.
